Last Ilford run when all the dealers were out of stock they could still get LF and ULF film from the distributor. You might call Denis or Fred at the VC store and ask specifically if they have tried or would try their Ilford distributor. I can't remember the distributor's name. When they all have stock I think you will find the VC store has the best price and good service. Tel: 480-767-7105-Denis Mon-Friday open 11:00 AM eastern time.
The second thought would be to post a "wtb" here and in the LF Forum. If you are not a member there you need to sign up and wait 30 days to post ads. Much of the 7x17 film I use has come out dated from other people’s freezers at a reduced price but in excellent working condition.
